SPECIFICATIONforming part of Letters Patent No. 408,715, dated August 13, 1889.

Application led March 15, 1889. Serial No. 308,431 (Model.)

To all whom t may concern,.-

Be it known that I, LovREN E..HOGUE, a citizen of the'United States, residing' at Greenville, in the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Injectors for Steam- Boilers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, making a part of this specification, and to the letters and figures of reference marked thereon.

This invent-ion relates to certain new and useful improvements in injectors of that class known as single-barrel injectors, with the exception that this' is not a restarter.

The invention consists in the peculiarities of construction andthe combination s, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the drawing', and then particularly pointed out in the appended claim.

The invention is clearly illustrated in the accompanying drawing, which represents a central section th rough my improved injector.

Referring nowto the details of the drawing by letter, A designates the shell; B, the steaminlet; C, the water-inlet; D, the overflow, and E the connection to the boiler. The end of the shell adjacent to the steam-inlet is formed with a recess @,in which is fitted the annular ilange h on the end of the nozzle c, formed with a steam-chamber d, and within this nozzle, with its annular flange e on it seated in passes to exhaust the air from the space C or A Waterlsupply pipe.

What I claim as new is- In an injector, the combination, with the shell A, formed with the seat h, of the nozzle Ac, the tube F, extended through said nozzle and having tapered end, as shown, with a passage z' around the tube at the end of the nozzle c, the tube H, having its inner end elnbracing the tapered end of `the tube F and guided by the walls forming said seat h, and the valve on the other end of the tube I-I and bearing on said seat, substantially as shown and described.,

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
